Record high temperatures today and muggy conditions mean we have an unhealthy air alert from 11 a.m. to 11 p.m. today. Highs will reach 94 degrees and it will be muggy. There is a slight chance of afternoon thunderstorms as well.

The air quality alert is because of expected high levels of ozone that may cause breathing difficulties for people who have asthma, respiratory disease or the very old. Stay inside in a cool, air-conditioned building if possible.

Don't expect it to cool down much tonight as highs might not go below 70.

We should shatter the record high temperatures for today. The record high for Boston is 91 set in 1936 and Worcester is 90 set in 1906. There might actually be some parts of the Connecticut Valley and MetroWest that rise to the upper-90s!

And when those storms come through late today or this evening they could have strong winds and lightning.

Tomorrow still looks very warm - a high of 81 - but not as bad as today.
